title: [Rasch analysis on stroke-specific quality of life (SS-QOL) scale of acupuncture intervention on stroke].
abstract: OBJECTIVE
  To optimize the evaluation level of active motor threshold and the functional domain of upper limbs of stroke-specific quality of life (SS-QOL) scale with Rasch analysis.
  
  
  METHODS
  Sixty patients with acute ischemic stroke that were in accord with research criterid were randomly divided into a test group (30 cases) and a control group (30 cases). Acupuncture treatment and routine western medicine were applied on the test group, and single treatment of routine western medicine was applied on the control group. Selected acupoints were MS 5, Fengchi (GB 20), Hegu (LI 4), etc. Active motor threshold and the functional domain of upper limbs of SS-QOL were self-tested by patients after one treating course. The characteristics of the above mentioned items were tested with Rasch model.
  
  
  RESULTS
  The statistical result on fitness of active motor threshold and the functional domain of upper limbs of SS-QOL showed that every reference of samples and items wosin accord with the Rasch model and has well inner reliability and validity. The Infit and Outfit MnSq values of active motor threshold and the functional domain of upper limbs of SS-QOL are basically between 0.5 and 1.5.
  
  
  CONCLUSIONS
  The application of Rasch analysis on the assessment of patient reported outcome (PRO) has optimized the PRO scale (the activity and upper limb function domain of SS-QOL scale) and enhanced evaluation level of active motor threshold and the functional domain of upper limbs of SS-QOL scale.
